A sealed test type blood collection tube cap device

Abstract

This utility model relates to the field of blood collection tube technology and discloses a sealing test type blood collection tube cap device, including a test platform and a cap body. A test groove is vertically formed on the upper surface of the test platform. The sealing end of the cap body matches the size of the test groove. An inflation tube is fixedly installed on the upper side of one side of the test platform. This utility model allows the sealing end of the cap body to be inserted into the test groove. Controlling the electro-hydraulic actuator pulls a piston downwards, which in turn pulls a pressure block downwards via a connecting rod, pressing against the end of the cap body located outside the test groove. This secures the cap body, preventing it from loosening during testing and affecting detection accuracy. After the cap body test is complete, the electro-hydraulic actuator pushes the piston upwards, and the end of the connecting rod near the piston automatically pushes the cap body out of the test groove, facilitating its collection.

Description

Technical Field

[0001] This utility model relates to the field of blood collection tube technology, specifically a sealing test type blood collection tube cap device. Background Technology

[0002] In the field of medical testing, blood collection tubes are crucial tools for blood sample collection and preservation, and their sealing performance directly affects sample quality and the accuracy of test results. Defects in the sealing of blood collection tube caps can not only lead to sample leakage and contamination, but may also affect sample composition due to gas exchange, thereby interfering with the accuracy of subsequent biochemical analysis or genetic testing.

[0003] The inventors have discovered that at least the following problems remain unresolved in the prior art: during the testing of blood collection tube caps, the caps are prone to improper installation and loosening during the testing process, which affects the testing accuracy of the blood collection tube caps. Furthermore, after the blood collection tube caps are tested, they need to be manually removed, which is cumbersome and can easily damage the caps.

[0004] Therefore, we propose a sealing test type blood collection tube cap device to facilitate cap fixation during testing and collection after testing. Utility Model Content

[0005] The purpose of this invention is to provide a sealing test tube cap device, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing test type blood collection tube cap device, including a test platform and a cap body. A test groove is vertically formed on the upper surface of the test platform. The sealing end of the cap body matches the size of the test groove. An inflation tube is fixedly installed on the upper side of one side of the test platform. A pressure sensor is fixedly connected to the upper side of the inner wall of the test groove away from the inflation tube. A pressure block is set directly above the test groove. The device also includes a control mechanism for controlling the fixing and disassembly of the cap body.

[0007] As an optional solution to the technical solution of this application, the control mechanism includes a connecting rod and an electro-hydraulic push rod. A piston is slidably connected inside the test tank. One end of the connecting rod vertically passes through the middle of the piston and is fixedly connected to the piston. The telescopic end of the electro-hydraulic push rod is fixedly connected to the bottom side of the piston. The end of the connecting rod away from the piston is fixedly connected to the middle of the upper surface of the pressure block.

[0011] As an optional solution to the technical solution of this application, the electro-hydraulic actuator is fixedly connected to the bottom inner wall of the test tank, and an industrial control computer is installed below the side of the test platform where the inflation pipe is installed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the sealing end of the cover body can be inserted into the test groove, and the electro-hydraulic push rod can be controlled to pull the piston downward. The connecting rod can pull the pressure block downward, which can press against the end of the cover body placed outside the test groove, thereby fixing the cover body and preventing it from loosening during the test, which would affect the detection accuracy.

[0017] Please see Figures 1-2This utility model provides a technical solution: a sealing test type blood collection tube cap device, including a test platform 1 and a cap body 12. A test groove 11 is vertically formed on the upper surface of the test platform 1. The sealing end of the cap body 12 matches the size of the test groove 11. An inflation tube 13 is fixedly installed on the upper side of one side of the test platform 1. The air outlet of the inflation tube 13 is connected to the upper end of the inside of the test groove 11. A solenoid valve 14 is installed inside the inflation tube 13. A pressure sensor 15 is fixedly connected to the upper part of the inner wall of the test groove 11 on the side away from the inflation tube 13. A pressure block 17 is provided directly above the test tank 11, and a control mechanism for controlling the fixing and disassembly of the cover body 12 is also included. The control mechanism includes a connecting rod 2 and an electro-hydraulic push rod 21. A piston 16 is slidably connected inside the test tank 11. One end of the connecting rod 2 vertically passes through the middle of the piston 16 and is fixedly connected to the piston 16. The telescopic end of the electro-hydraulic push rod 21 is fixedly connected to the bottom side of the piston 16. The end of the connecting rod 2 away from the piston 16 is fixedly connected to the middle of the upper surface of the pressure block 17. The electro-hydraulic push rod 21 is fixedly connected to the inner wall of the bottom end of the test tank 11.

[0018] In this technical solution, the sealing end of the cover body 12 can be inserted into the test groove 11, and the electro-hydraulic push rod 21 is controlled to work, which can pull the piston 16 to move downward. The connecting rod 2 can pull the pressure block 17 to move downward, which can press against the end of the cover body 12 located outside the test groove 11, thereby fixing the cover body 12 and preventing it from loosening during the test, which would affect the detection accuracy. It should be noted that the size of the test groove 11 is the same as the inner diameter of the blood collection tube that matches the cover body 12. When the sealing end of the cover body 12 is inserted into the test groove 11, the end of the connecting rod 2 near the piston 16 is retracted into the test groove 11, which does not affect the insertion of the cover body 12 and the test groove 11.

[0019] In this embodiment, a connecting groove 22 is vertically provided at the lower end of the inner wall of one side of the test groove 11. The bottom end of the connecting rod 2 is slidably connected to the connecting groove 22. A pressure sensor 23 is fixedly connected to the inner wall of the bottom end of the connecting groove 22. An industrial control computer 24 is provided below the side of the test bench 1 where the inflation pipe 13 is installed.

[0020] In this technical solution, when the electro-hydraulic push rod 21 pulls the piston 16 downward, it can drive the connecting rod 2 downward, causing the bottom end of the connecting rod 2 to press the pressure sensor 23 on the inner wall of the bottom end of the connecting groove 22. The pressure sensor 23 can transmit data to the industrial control computer 24. Furthermore, the industrial control computer 24 can automatically control the solenoid valve 14 to open, and inflate the test groove 11 through the inflation pipe 13. Through the air pressure sensor 15 on the inner wall of the upper end of the test groove 11, the air pressure change in the test groove 11 can be monitored, and the sealing performance of the cover body 12 can be further accurately tested. It should be noted that the air inlet end of the inflation pipe 13 is connected to the air outlet of the corresponding inflation pump, and a sealing ring is provided on the outside of the piston 16.

[0021] In this embodiment, the pressure block 17 is movably connected to one end of the cover body 12 located outside the test groove 11, the connecting rod 2 is matched with the size of the test groove 11, and the end of the connecting rod 2 near the piston 16 is movably connected to the sealing end of the cover body 12.

[0022] In this technical solution, after the cover body 12 has been tested, the electro-hydraulic push rod 21 is controlled to push the piston 16 upward. The end of the connecting rod 2 near the piston 16 can automatically push the cover body 12 out of the test slot 11, which facilitates the collection of the cover body 12 and reduces the labor intensity of the staff. It should be noted that the amount of compressed air injected into the test slot 11 does not need to be too much, so as to avoid the cover body 12 being blown away when the connecting rod 2 pushes it out.

[0023] When using a sealing test type blood collection tube cap device, the sealing end of the cap body 12 can be inserted into the test groove 11. The electro-hydraulic push rod 21 is controlled to pull the piston 16 downwards. This, via the connecting rod 2, pulls the pressure block 17 downwards and presses it against the end of the cap body 12 located outside the test groove 11, thus fixing the cap body 12. Simultaneously, the bottom end of the connecting rod 2 presses against the pressure sensor 23 on the inner wall of the bottom end of the connecting groove 22. The pressure sensor 23 then transmits the data to the industrial control computer 24. The step-by-step control computer 24 can automatically control the solenoid valve 14 to open, and inflate the test tank 11 with air through the air inflator 13. The air pressure sensor 15 on the inner wall of the upper end of the test tank 11 can monitor the air pressure change in the test tank 11, and further accurately test the sealing performance of the cover body 12. After the cover body 12 is tested, the electro-hydraulic push rod 21 is controlled to push the piston 16 upward. The end of the connecting rod 2 near the piston 16 can automatically push the cover body 12 out of the test tank 11, which facilitates the collection of the cover body 12 and reduces the labor intensity of the staff.
